Animal Genetics 44, 2, 227-230 (IF=2.584) My contribution to the multi-author articles generally included: the idea and the plan of research, writing of the publication and pedigree analysis, while the contribution of co-authors consisted of making a laboratory part of the projects. Detailed information on the participation in each of the co- authorships is given in Annexes 4-6. B) Short description of the scientific / artistic achievement outlining the scientific goal and the results received, together with an indication of their potential use Multi-generation pedigrees are a valuable source of information about an animal and its ancestors, but their wider use in scientific studies was only enabled by the development of computer technology. From the 1990s, a series of papers devoted to the analysis of different species of domestic animals and wild species kept in captive breeding have been published. The aim of these analyses was to define ancestors of populations studied, to restore population history and to estimate genetic diversity. Pedigree measures were also used to evaluate the way of population managing, to show directions of 2

its development and to identify genetically important representatives of the population, significant from the point of view of a conservative breeding. My analyses are a part of this important area of research. The objects of the studies were three populations of pedigreed animals: purebred Arabian horses and Polish Hound and Hovawart dog breeds. A common feature of the populations is their small size, and important advantage is the relatively large amount of pedigree information available, from a few to about 20 ancestral generations. The aim of the study was to evaluate genetic diversity of the populations and to answer the important questions raised by breeders. In some projects, the results of which I present as a significant scientific achievement, pedigree analysis has been supplemented by the analysis of mitochondrial DNA, used to answer the questions being beyond the scope of the pedigree analysis itself. In general, mtDNA studies in horses and dogs, which mainly concern the phylogenetic, taxonomic and forensic issues, are conducted so far in a relatively small area. For example, according to Verscheure et al. (ZooKeys 2013), only 58 articles presenting results of mtDNA studies in dogs were published in the world between 1995 and 2013. In this niche research area my articles, referring to the origin of a population and verification of pedigrees and genetic diversity of the population, can be found. *** The basic source of information in pedigree analyses are pedigrees, and a necessary condition to obtain a reliable results are their reliability and completeness. Unfortunately, for obvious reasons, the amount of pedigree data are limited and at most cover the period described in studbooks. In turn, the credibility of the data results from a specifics of breeding of a given animal species and a history of a breed. Together with the development of molecular methods, a parentage control, carried out on the basis of genetic marker analysis, has become an essential step in breeding of many breeds of domestic animals to ensure the accuracy of their pedigrees. However, due to a lack of biological samples from further ancestors, nuclear markers can be used exclusively for verification of records from the closest generations in a pedigree. A tool that allows to verify historical records is mitochondrial DNA (mtDNA), which is inherited only in the female line, and thus allows the evaluation of exactly these lines. Samples taken from present-living animals are used in the laboratory analysis, and a research scheme is as follows: assignation of dam lines present in the population on the basis of the whole pedigree data, choosing representatives of particular lines and their branches to mtDNA analysis, and finally laboratory analysis of mtDNA. A verification is possible only if a line has different branches. In practice, the interpretation of the results is based on the basic assumption that in principle pedigrees are true, and the errors are the exception (their effective verification would not be possible while assuming the opposite, i.e. that the pedigrees contain numerous errors). Evaluation of results of the 3
